Title: Aqueous emulsion fuels from petroleum residuum-based fuel oils
Inventor: GUNNERMAN RUDOLF W
IPC: C10L1/32
Filed: 1999-04-22
Abstract: An aqueous macroemulsion to be used in place of petroleum residuum-based fuel oils such as No. 4, No. 5, and No. 6 fuel oils, as well as the vacuum residuum from the fraction distillation of petroleum, is formed by emulsifying the fuel oil with water or an aqueous liquid, the fuel oil forming the dispersed phase and the aqueous liquid forming the continuous phase. An emulsion stabilizer, and optionally various other additives, notably a lower alkyl alcohol, are included to stabilize the properties of the emulsion. The emulsion is prepared by heating the fuel oil, particularly No. 6 fuel oil, and the water to a temperature above about 60 ~C, and combining the two heated liquids in an appropriate ratio and shearing the mixture to form the macroemulsion. The macroemulsion offers numerous advantages over the fuel oil itself including the fact that it can be pumped at ambient temperature rather than requiring heating, and that it is a clean-burning fuel with significantly lower emission of NOx and other pollutants and contaminants.

Title: Apparatus for resonant excitation of high frequency alternator field
Inventor: TUPPER CHRISTOPHER N
IPC: H02P9/30
Filed: 1998-12-22
Abstract: A poly-phase high frequency alternator (10) with a low-loss magnetic core is excited by a low-loss field coil (18) that is part of a series resonant circuit tuned to a desired AC power frequency which may be 50 or 60 Hz. The series resonant circuit is excited at the resonant frequency. The resulting resonant behavior automatically provides the high driving voltages and sinusoidal energy storage patterns needed to efficiently modulate the field inductance at 50 or 60 Hz. Modulating the field at the desired AC power frequency modulates the alternator output voltage at that frequency. The poly-phase alternator output is rectified (46) into a single phase and commutated with respect to the load at the zero crossing of each half cycle of the AC power frequency. This produces a single phase power frequency AC  output (56).

Abstract: An improved method and system for initializing the logical units (LUs) in a Gateway between an SNA network having a mainframe host computer and another network. An activation procedure derives the Table of Boundary LUs on the mainframe host computer by noting the device logical unit numbers within the set of 'Activate Logical Unit' (ACTLU) SNA Request Units. If the mainframe host computer includes an LU in its Table of Boundary LUs, then the activation procedure creates a corresponding LU in the Gateway. The activation procedure also marks each of the created LUs in the Gateway as active. The newly created LUs are then added to the resource pool of LUs available to the network. Additional aspects include a method for assigning a logical unit type to an LU based upon whether a Bind request is received from the mainframe host computer within a certain amount of time after sending a positive sense code to the mainframe host computer.
